It's not a joke. the chickens are no longer cool and literally pointless now. Chickens are braver now and don't disperse like they used to.

Totally dumb update. A faction of people wanted the chickens changed, majority didn't and CS:GO needs all the help it can get. I personally think it's better than CS:S but with updates like this Valve is just shooting themselves in the foot. Now all it is is bitching about how they ruined the chickens. I think Valve has forgotten how to make a good game, much less support it.
